spikes (shoes) should fit just like trainers. some sizes can vairy tho so go to a shop and try pleanty on!

usually the spikes are the same size as your running shoes.

They should fit like a glove, but not too tight so they hurt.

The spikes can not slip on your foot.

Try on different shoes so you get a pair that fits.
